Study hypothesis

Indomethacin is known to be a strong inhibitor of ovulation in the spontaneous menstrual cycle. Therefore we assume that the use of indomethacin prior to follicle aspiration in In-Vitro Fertilisation-treatment in the Modified Natural Cycle (IVF-MNC) significantly decreases the number of patients with one or more premature ovulations compared to placebo.

Ethics approval

Approval received from the local medical ethics committee (Medisch Ethische Toetsingscommissie UMC Groningen) on the 24th June 2005 (ref: 2005/074).
